Well I might feel different in another 6 months. I also have no proof there is OM and if there is she not flaunting it in front of my face or introducing him to my kids. If/when that happens I am out. That aspect does make it easier for me to handle.
I agree less is more, better to keep your mouth shut. Your kids are young, you guys will be in each other's lives for a long time to come. It would be much easier to handle if you are civil towards each other.
I don't know if I can stand for years. I just take it a day at a time, doing things for me, moving on with my life and approaching it like we are divorced. Even if I was D'd I wouldn't be dating yet so I am really not doing anything different right now vs if my D was final.
Us technically being married still lingers in the back of mind but that light is very dim.
